Dear Sir/Madam,

I am getting a warning while finding an inverse of a matrix as follows: Warning: Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 1.024137e-017 how to resolve it?

your matrix is singular.it means that it's determinant is close to zero or actually zero.or even perhaps if you are sure that it's non-singular ,round off errors may result this warning.. check your matrix to see if it's invertible or not...
